Do you have a ip locking device? It is to be installed in place of the 17mm plug in the side of the drivers side of the injection pump. When the lock is installed it presses against a notch in the cam in the injection pump which is only seen at 15' degrees ATDC. I would set the motor at 15 degrees ATDC and remove the plug and using a mirror look inside the pump and see if you can see the notch on the cam in the pump. Sometimes i haven't had good luck with drip timing, everyone has a different idea of whats correct and whats not correct with drip timing.
